Wind turbines are prominent visible symbols of renewable energy. In the last few years Texas has become a world leader in wind energy and has more installed capacity than most countries. With increasing numbers comes a greater likelihood that they are sited near rural residences and more populated areas. Wind energy planners make efforts to manage the noise impact, which they maintain compares favorably with various benign noise sources. Some wind farm neighbors however find the noise highly objectionable, some claim loss of sleep, and a few allege catastrophic medical complications. During the talk I will briefly compare wind turbines to other environmental noise sources, examine the unique factors affecting wind turbine sound levels and annoyance, review actual data and audio, and explore reasons that otherwise well-planned wind farms may still disturb nearby residents.
